IMPROVEMENT lN FEED-WATER HEATERS.

Specification forming part of Letters Patent No. 159,728, dated February 9, 1875; application filed January 13, 1875.

To all whom it may concern:

Be it known that I, ROBERT WETHERILL, of Chester, in the county of Delaware and in the State of Pennsylvania, have invented certain new and useful Improvements in Feed- Water Heaters; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates particularly to devices for heating water by exhaust steam from engines for feeding boilers, but may also be used for cooling or distilling purposes; and the nature of my invention consists in the combination of two or more pipes forming a series or coil, and having their ends connected with the main pipes, for the purpose of dividing the material to be acted upon, and increasing the amount of surface to be acted upon, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertainsto make and use the same, I will now proceed to describe its construction and operation, referring to the I annexed drawing, in which- Figure l is a side view, and Fig. 2 an end View, of my invention. Fig. 3 represents my invention as applied to a steam-engine.

A A A represent three continuous pipes or tubes forming a coil, as shown, the ends of said pipes being connected to the main pipes B and 0, respectively, one being the inlet, and the other the outlet, pipe. The material that passes through these pipes to be heated or cooled, or acted upon in any way, is thus divided into small bodies, thereby being easier heated, cooled, or distilled, as the case may and is heated to 212 Fahrenheit.

be. A greater surface to be acted upon is also obtained thereby. In dotted lines in Fig. 3, a represents a bed. upon which is placed an ordinary steam-engine cylinder, 12, with the usual piston, piston-rods, Ste. 0 represents the exhaust, which opens into a casin g, within which my invention is placed. From the pipe B extends a pipe, D, leading to the steampump. From the pipe 0 extends a pipe, E, leading to the boiler.

My device is to be used principally for heating cold water by the exhaust steam from an engine. By forcing the water to be heated through the coils A by means of a pump the water is divided in small particles or streams,

This degree of heat is hardly attainable when a single pipe is employed.

In the common way of fastening a single pipe in the ends of the heater leakage often occurs; but by having one continuous, such is not liable to be the case.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, in a feed-water heater, of the pipe B, two or more pipes, A, extending therefrom, and formed into coils, with their ends brought down through the coils, and terminating in the pipe 0, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of December, 1874.
